Our mission: Give every founder, freelancer, and entrepreneur instant access to professional-grade financial calculators — completely free, no signup required.

RateKit runs on free coffee and the mild delusion that these calculators actually help people. If one of them just saved you from a spreadsheet disaster, you could buy me an actual coffee — or don't, no popups, no guilt trip, I promise. Ko-fi · Patreon.
